Specication o1' Letters Patent. Patented June 18, 1918.

Application filed January 5, 1915. Serial No. 655.

'an original and two copies of an entry may be ma e by one and the same writing operation. It is the general purpose of this invention to provide a book of this kind which is extremely convenient to manipulate and which will permit the operator to retain in a convenient arrangement one set of duplicates of each sheet. A further object of the invention is to accomplish these results in a construction and arrangement of parts whereby and wherein the manufacturing cost is reduced to a minimum.

In both of the embodiments of my invention disclosed herein there is contemplated the use of a series of transparent sheets on the under surface whereof a record is made by means of a composition carried by a carbon or transfer sheet.

These transparent sheets are preferably united with the orginal vsheet into a double leaf, which double leaf is preferably provided with a single stub whereby the leaves may be stapled or otherwise secured to gether to form a pad, together with the triplicate sheets, which triplicate sheets may also lbe provided with stubs whereby the may each be bound or stapled into the pa together with adouble leaf. In one modification of my invention,the heading is for the original, duplicate and triplicate sheets as printed on the ends thereof which are adjacent to the stubs, `a sheet of carbon or transfer paper having transfer material on both sides thereof being preferably secured at the opposite end of the pad from the stubs. In the other modication of the invention, the 'arrangement of the original, duplicate, triplicate and carbon 'sheets 1s the same as just described, but the heading sheets are printed'at'the opposite ends of the sheets, thus having the stubs at the bottom of the sheets.

In carrying out my to employ for the ori 'nal and duplicate sheets a single leaf w ich is folded and provided with severing lines in such manner that the duplicate shall carry the binding stub and to treat the duplicate in such manner as to render it transparent-pref erably by the use of oleaginous substances (such as melted petrolatum) rather than to use the ordinary commercial grades of invention I prefer transparent paper, such as parchment or j manifold tissue. This enables me to use a comparatively cheap paper in the original and in the duplicate and avoids the necessity of using different kinds or grades of paper in the book or pad; it also enables me, as a practical, economical and commercial proposition, to embody the original and the duplicate sheets in a single leaf. If, for instance, it were proposd to use a commercial transparent material such as mentioned, in both the original and duplicate sheets, the cost of such paper would be i much greater than that of ordinary book paper or news paper such as 1s usually employed in manifold books and which can be rendered transparent in the manner described herein at a comparatively slight cost.

In the drawings forming Figure 1 represents a perspeetlve view of one form of book or pad embodying my invention; Fig. 2 is a longitudinal sectional view through said book or pad; Fig. 3 is a detail elevation of the upper end of said book or pad the original and duplicate be-V ing turned back to reveal the triplicate and carbon sheet; Figs. 4, and 6 perspective views illustrating successive steps in` the manipulation of the books or pad; Fig.y

7 is a view, similar to Fig. 1, of another form of book or pad embodying my invention; and Figs. 8, 9 and 10 are perspective views illustrating successive steps 1nY the maiipulation of the last mentioned book or pa Describing by reference characters the various parts illustrated herein, 1 denotes the original and 2 the duplicate sheet, said sheets being preferably united by a seven ing line 3 and the duplicate sheet being provided with a stub part hereof 4 to which it is united by a severing line 5. For convenience of manipulation, the original sheet maybe made somewhat shorter than the duplicate sheet, whereby some clearance will be provided between the severing line 5 and the adjacent or upper and of the original, Vas indicated at 6 (see Fig. :2).

7 denotes a triplicate sheet which is under thev leaf just described and .which isr provided with a stub 8, preferably withoutl the use of a severing line therebetween. The alternating stubs projecting from the duplicate and triplicate sheets 'may be convene iently stitched or stapled to a back 9, and this back may be provided with an eXtension forming a cover 10, shown herein as a back of sideffolding cover connected tothe Secured an intermediate side portion 11.

y to the lower end of the back 9 is a carbon or transfer sheet l2 which. is coated on both sides with transfer material, as pencil car.- bon. It is evident that the sheet 12 Vmay be lsecured tothe bottom of the pad in any other desired or convenient manner. F urthermore, in certain cases, it may be desirable .to secure the carbon ,sheet to the side ofthe parl i Inoperation, and referring more particularlyto the embodiment of the invention shown in Figs. l to 6 inclusive, the top leaf j comprising the original and duplicate sheets 1 and 2 will be lifted and the transfer sheet 12 will be interposed between the duplicate sheet 2 and the triplicate sheet 7. For convenience of manipulation either or both upper corners of the carbon sheet 12 lmay be cut away, as indicated at 13, and each triplicate sheet is provided with a notch in the upper right hand portion thereof, ias indi.- cated at 14. With theA parts thus arranged,

`the operator writes his entries upon the u sheet 1, thereby simultaneously making the same yrecord upon the duplicate Aand triplicate sheets,the record of the Vduplioriginal cate being made upon the under or reverse side `thereof from the transfer material on the upper surface of .the carbon sheet, but thisrecord being clearly legible through the du rv.licate lsheet because of itsV transparency, o

while the record lon thetriplicate sheet -is Vinadein the Ordinary manner, by transfer from the lower surface o f the carbon sheet Y upon the appel1 .Surface of the trpleate sheet, l.The operator vcan then tear olf the original and fluploate Sheet from theetub 4C. Then, inserting his `thumb linto thenotch 14., leeA een eorlveeeHtlvV grasp the original sheet 1 beneath the carbon sheet (as shown in Fig.l 3) and, by pulling downwardlyY upon the original sheet and moving upwardly in the manner shown in Figs. 41: and 5, can throw the used triplicate sheet 7 back out of the way in the manner shown in Fig. 5. This enables the carbon sheet to be conveniently inserted above, and in fact to drop vready for the next operation,

upon, the neXt unused triplicate sheet (see Fig. 5) and the leaf comprising the unused original and duplicate sheets will automatically drop in place upon the carbon sheet, i (see Fig. 6)

The triplicates will be preferably secured vto andv integral with their stubs, whereby a pad of such triplicates may be kept; or, if desired, they may be torn from their stubs and filed away yfor use. In the latter case, however, I preferto construct the pad in the manner shown in my application No.-

2819, filed January 18, 1915. y

In Figs. 7 to l0 inclusive', there is shown a modification of my invention which differs from that just described onlyin placing the headings of the original, vduplicate and triplicate sheets at the ends, opposite thoseindicated in the preceding views, and.

to l0, from which may be seen that3 as soon as a new leaf comprising an original and a duplicate sheet has beenlifted a certain distance, the used triplicate, the kcarbon sheet, and the new leaf will drop automatically into their .respective places, readyrfor the next operation,

lteleeled, the original ae) Well aS the duplicate Sheet may be provided With a de.- tachable stub. In fact, this provides amore Convenient arrangement for Ylelnelps the` leaves into pad form*k than an arrangement a wherein the duplicate Sheet only .is provided With Seth Stab?l 1p manipulating `a pad wherein the originale are eo providedwth. Stubethe Sheetev Will be mapipulatedftem .l

what s ordinarily vthe lower or bottom end of the pad, the triplicate sheetof each series and the carbon sheet in this case being both notched attlie lower rghthand corner to pialptA Convenient aoeeee to the original sheet of the series next therebeireath.jV The 1 Y orlslealand the dapleiateimay be asl-eene* Veneetly torn or .Severed from theirstubs as the duplicate yalo/ne;v Y l v For Convenience ofjdescription and incrder to distinguish between aleaf comprisl ing anoriginal and far duplicate sheet made from'the same pieceV of paper and a. leaf comprsingan original-and. a rduplicate sheetmade of diferent pieces of paper, yI haveapa plied the term `unitary toA therst kind off leaf., although I de not wish to be understood as thereby limiting my inventionto the firsts;

mentioned kind of leaf, except as such limitation may be positively included in the claims hereto annexed or as this limitation may be rendered necessary by the state of the prior art. For instance, it may be p0S-' sible to make a leaf from two pieces of paper pasted together and to use transparent paper for the duplicate; or the leaf While made from a single piece of paper, may be made from transparent paper whereby the original and the duplicate will be transparent. I consider that either of the leaves just described are Within the purview of my invention.

Furthermore, I do not wish to be understood as requiring', in the realization of my invention, that the entire duplicate sheet shall be transparent, as it is evident that only the copy-receiving part thereof need be transparent.

Having thus described my invention, What I claim is:

1. A book of the character described comprising series of original, duplicate and triplicate sheets, the original and duplicate sheets of each series being detachably united at one end and the duplicate being transparent and provided with a detachable stub and the triplicate sheet of each series being located beneath the original and duplicate sheets and also provided with a stub; and a sheet of transferring material coated on both sides and adapted to be interposed between the duplicate, and the triplicate sheets of each series, the triplicate sheet being notched to permit convenient access to the original sheet of the series therebeneath.

2. A book of the character described comprising series of original, duplicate and triplicate sheets, the original and duplicate sheets of each series being detachably united at one end and the duplicare being transparent and provided With a detachable stub proj ecting beyond the adjacent end of the original sheet, and the triplicate sheet of each series being located beneath the original and duplicate sheets and also provided with a stub; and a sheet of transferring material coated on both sides and adapted to be folded between the duplicate and the triplicate sheets of each series, the triplicate sheet being notched to permit convenient access to the original sheet of the series therebeneath, the sheet of transferring' material being adapted to be folded or dropped between the sheets at the free ends thereof.

3. A book of the character described comprising series of original, duplicate and triplicate sheets, the original and duplicate sheets of each series being detachably united at one end and comprised within a unitary leaf, the duplicate being transparent and provided with a detachable stub and the triplicate sheet of each series being located beneath the original and duplicate sheets and also provided with a stub, and a sheet of transferring material coated on both sides .and adapted to be inserted between the duplicate and triplicate sheets of each series, the triplicate sheet being notched to permit convenient access to the original sheet of the series therebeneath.

4. A triplicate manifolding pad comprising series of original, duplicate and triplicate sheets of paper and an interleaving sheet of transferring material coated on both sides, the original and duplicate sheets of each series being detachably united at one end and formed from a unitary leaf, the duplicate sheet being provided with a detachable stub, and having the body portion thereof transparent, the triplicate sheet of each series also having a stub and provided with a notch, and means fastening the sets together to form a book or pad.

A triplicate manifolding pad comprising series of original, duplicate and triplicate sheets of paper and an interleaving sheet of transferring material coated on both sides, the original and duplicate sheets of each series being detachably united at one end and formed as parts of a, unitary leaf, the duplicate sheet being provided with a detachable stub and having' the body portion thereof transparent, the triplicate sheet of each series also having a stub and being provided with a notch and the carbon sheets being notched or shortened to permit access through said sheet and the triplicate sheet to the original of the series therebeneath.
